The summer air in Kuoh Town hung thick and humid, but within the confines of the Occult Research Clubroom, a different kind of heat was brewing.
Rias Gremory, Heiress to the Gremory clan, stood before Mitarai, her posture deliberately accentuating the devastating curve of her rocket breasts beneath her uniform.
"We're going to the Underworld," she declared, her voice a blend of pride and a faint, uncharacteristic flush coloring her cheeks.
She leaned in, peering into Takashi Mitarai's eyes. "Now is not the time to stare at my chest, but to listen."
Mitarai forcibly dragged his gaze upward. The Underworld? The ancestral domain of devils and fallen angels? A flicker of practical concern cut through the haze of his usual lust.
He was a newbie devil. Wouldn't there be… complications? Territorial disputes? A literal disintegration of his mortal form?
He voiced his concerns, and Rias waved a dismissive, elegant hand. "There is no problem. You are of my peerage. A visit under the auspices of our pact is above reproach." A smirk, both arrogant and protective, touched her lips.
"And even if some fool dared to question it, I doubt any devil is suicidal enough to lay a finger on the next head of the Gremory Marquis family. Still…" Her expression sobered slightly.
"I will guide you within Gremory territory. Be cautious. Not all of my kind are… kindly disposed."
And so, by the whim of a beautiful devil, Takashi Mitarai's summer vacation was destined to be spent in the depths of the Underworld.
…
"I orchestrated the introduction, but I never imagined you would actually seduce my mother," Rias breathed, her voice a mix of exasperation and dark arousal.
From beside her, Venelana Gremory let out a throaty, satisfied laugh. "Hehe~ Thanks to you, Rias, I now have a secret husband in Takashi-kun, and his child growing in my belly. A woman could not ask for more."
…
In Rias's opulent bedroom within the Gremory mansion, the air was saturated with the sweet, mingled scents of perfume and sex. Mitarai lay naked on the vast bed, his body a landscape recently conquered.
Pressed against him on either side, equally bare, were Rias and Venelana, their limbs sinuously intertwined with his and each other's.
Their massive, soft breasts were crushed against his chest, the stiffened peaks of their nipples digging into his skin with a tantalizing pressure. The heat from their bodies was immense.
"You are a lucky man," Rias purred, tracing a fingernail down his sternum.
"To claim a beautiful mother and daughter as your own." Her eyes sparkled with wicked intent.
"Though, if my mother is your secret wife… that would make you my step-dad, wouldn't it? How about it? Shall I call you 'daddy' while we're here in the Underworld?"
Venelana sighed, a sound that held no true reproach. "Oh dear, what a troublesome girl." The relationship between the two devils was far from strained; they were alike in countless ways, from their formidable power to their acquired tastes.
The mother's chiding was merely a part of the game, one she clearly relished.
Mitarai's hand slid to grip Venelana's hip. "I suppose I'll allow it. Though the concept of a daughter older than me is still… novel."
"And it's hard for a daughter to have such a naughty step-dad," Rias countered, her hand drifting downward.
"Look at you, growing so hard just from the sight of her. This raging cock is too much for one woman to handle, don't you think?"
"She's right," Venelana murmured, her own hand joining her daughter's.
"It is a wife's duty to see to her husband's needs. Please, allow us to serve you together."
Four slender, devilishly soft hands descended upon his throbbing erection.
His cock stood achingly hard, the broad, flushed head already glistening with precum. The heat it radiated was palpable even through their touch. They gathered the slick fluid, smearing it along his length with synchronized, practiced strokes.
The wet, obscene sound of their hands working his shaft—schlick, schlick—filled the room, a lewd melody that tightened his balls.
Mitarai gritted his teeth, clenching internally to stave off his climax, which only forced another thick strand of pre-cum to weep from his tip.
Soon, both women's hands were slick and shiny with his essence. His hips gave an involuntary jerk.
"A true woman-killer," Rias whispered hotly into one ear, her breath a brand. "This is the cock that stole the infamous Venelana Gremory from her husband."
"So long, so thick," Venelana sighed into the other, her tongue tracing the shell of his ear.
"The crown is so pronounced… designed purely to ravage a woman's depths. Any woman who knew of this would forsake her pride for a taste."
Mitarai's pride, stoked by their words, refused to let him remain their passive plaything. His hands shot out, each finding the full, yielding curve of an ass.
The textures were divine contrasts: Rias's was youthfully taut, perfect for a sharp slap that would make her gasp and clench around him. He'd taken her doggy-style many times, the stinging impact on that round flesh only heightening the feel of her tight, clutching heat.
Venelana's ass, in beautiful contrast, had a richer, heavier give, the softness of maturity. It was meant to be kneaded and gripped, to have his fingers sink in as he drove into her from below, their bodies pressed together in a seated embrace.
"Ah! Straight for the backside, you insatiable, handsome daddyr!" Rias giggled, pushing back against his palm.
"Please, use us as you wish, Master," Venelana cooed, her voice dripping with submissive promise.
"Our bodies are yours to command."
His questing fingers were not content with mere handfuls of flesh. They slid lower, through damp folds, to seek out the tightly furrowed pucker hidden between their cheeks—a frontier his cock had yet to claim, though his fingers were frequent, welcomed invaders.
The little rosettes, under his touch, twitched and clenched, as if with a mind of their own. He pressed a thick digit against Venelana's first, and with a slick, resisting pop, he was inside.
The channel, whose sole purpose was expulsion, was forced to accommodate him, distorting beautifully around the intrusion. The inner heat was immediate and intense, a narrow, intimate furnace.
"Nngh! Ah, not there… You mustn't… Anh! Your finger, gods…!" Venelana cried out, her body arching, her own dripping sex clenching rhythmically on nothing.
Rias watched, panting, as Mitarai's other finger began its own assault on her tight star.
"Fufu… to have his fingers claiming our assholes… My husband is such a calm, collected pervert. To be so lustfully precise, even with an old woman like me~!!"
The dual violation, the lewd symphony of their moans, the sight of the magnificent mother and daughter yielding utterly to his exploration, sent a final, undeniable surge of power through Mitarai's veins.
The Underworld, it seemed, held pleasures far beyond anything he had imagined. And he was just getting started.
Rias's scream tore through the room, a raw, unfiltered sound of overwhelmed pleasure as Mitarai's finger delved deeper, playing ruthlessly with her clenched, hot depths.
Yet, even as her bowels were invaded, her hands—and those of her mother, Venelana—never ceased their worship of his cock.
Rias's elegant fingers traced the throbbing head and sensitive frenulum, while Venelana's worked the thick, veiny shaft and heavy sac with practiced, possessive rolls.
Each time Venelana's index finger stroked the tense muscles of his perineum, a sharp, tingling bolt of electricity shot up Mitarai's spine. Rias's pace was maddeningly deliberate, not fast, but utterly precise, coaxing the backed-up cum to surge relentlessly up his urethra.
The sensation was amplified when Venelana's palm cradled his balls, her gentle kneading urging the squirming seed within toward its only exit.
Mitarai's hips began to jerk erratically, his breathing growing ragged and harsh.
